Please draw the cooling curve at standard pressure for benzene, C6H6 (MM = 78.01 g/mol). The normal freezing point of benzene is 5.00 oC, and the normal boiling point is 80.2 oC. Calculate the total enthalpyfor the process of converting 35.00 g of benzene vapor at 100.0 oC to solid benzene at -6.00 oC.

Please provide the work too, thanks!
